strange results in ippiWTFwd_32f_C1R

i have integrated "ippiWTFwd_32f_C1R" in my vc-project. every of the four result images exhibits the last row with some strange values as-1.#QNAN, 1.#QNAN, extremly big numbers or values that discord with the seemingly right ones above. Does anyone have a same problem?
